DEMOUNTABLE RIM FR VEHICLE-WHEELS.

ltor Vehicle-Vllheels, of which the following is a specification.

My invention relates to improvements in demountable rims for vehicle-wheels, and, more particularly, to means for attaching the tire riin tothe telly of the vehiclewlieel such as an automobile or the like, the saine being adapted to secui the rim, together with the tire carried thereby, upon the wheel-telly in proper position.

rlhe primary object .of the invention is to provide improved means whereby the rim and attached tire may be readily mounted upon and attached to or detached and demounted from the telly of the wheel while the tirel is in an inflated or expanded condition.

Another object of the invention is to provide a generally improved device of this class which will be exceedingly simple in construction, cheap of manufacture, and etlicient in use.

.The tire-rim may be of any suitable and convenient construction, but in the present embodiment of the invention and for the purpose oit this application, I have shown a rim of the clencher type, the device being admirably adapted for use in connection with a rim and tire of this class or type.

With the above mentioned objects in view, the invention consists in the novel construction, arrangement, and combination of parts, hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims. l

Referring to the drawings forming a part of this specification, Figure l is a cross sec- Y tional view of the telly and demountable rim portion of a wheel constructed in accordance with my invention. Fig. 2, a cross sectional view of the same with the improved demountable rim mounted in its normal position upon the wheel and locked thereon. Fig. 3, a side elevation of the telly with demountable rim attached, a portion of the rim and felly portions being broken away for the urpose of clearer illustration of the parts. ig. 4, a similar view of the `portion of saine provided with expandin device connected to the ends of the expanding ring.

Fig. 8, a side elevation of the preferred :torni of ring expanding device, a portion 'of the supportingsleeve being brokeny away and one o' the 4attached ends of the expanding rinor being sectioned for the purpose ot clearer illustration of the parts. Fig. 9, a side elevation of the supporting-sleeve carrying this form of ring-expanding device and the connected ends of the expanding ring.

-Similar numerals of reference designate like parts throughout all the figures of the drawings.

The vehicle-wheel 'elly 1, is 'provided with a circumferential groove 2, adapted to receive and contain an expanding ring or locking member 3, hereinafter described. The felly l, is preferably provided on its outer periphery with a metallic band or fixed rim it, suitably bent or fianged to conform to and form a lining for the groove 2, of the felly 1 The tire-rim 5, is adapted to be mounted and attached to or detached and demounted i'ron'i the elly of the wheel by 'means of the expanding ring or locking member 3, adapted to be expa ded or contracted within the groove by y suitable expanding and contracting means, of which means are shown in the accompanying drawings and hereinafter described.

V When it is desired to secure the tire-rim 5, upon the wheel-telly 1, the expanding ring or locking member 3, is adapted to be contracted within the groove 2, so that its outer peripheral surface will be :tlu'sh with the peripheral surface ofi4 the wheel felly 1:. The tire-rim is then free to be slipped or is securely attached or locked thereon .by expanding the expanding ring or locking .member 3.

memberinay engage with the inner periphery of the tire-rim 5, in any suitable and convenient manner, preferably, by providing an inner circumferential groove or pocket 6, adapted to receive and contain the expanding ring or looking member when the The expanding ring or loclging two forms mounted upon the wheel telly after which it y latter is in its expanded position. The ends l of the expanding ring or locking member 3, are, preferably, provided Wlth a sup- I porting-sleeve 7, adapted to slidably'receive l a pawl 15, on the and contain the ends 3a, and carrying the expanding device and adjacent parts in their proper re tive position.

The expanding ring or locking member 3, is, preferably, expanded and contracted by means of a threaded member 8, provided at its ends with oppositely-disposed or right and left handed threads taking into and operating Within internally-threaded boltopenings 9, in the ends 3, of the expanding ring or locking member. The kthreaded member 8, is provided with a pinion 8, meshing with a wormear 9, carried upon a transverse shaft or pm 10, said transverse shaft or pin 10, being carried in suitable bearing-openings 11, in the supportingsleeve 7. If desired, the expanding ring or locking member 3, may be expanded by means of a transverse expanding pinionbolt 12, interposed between and engaging with overlapplng racks 13, formed at the ends ofthe expandin ring or locking member as shown most carly in Fig. 6, of the drawings. The ends of the expanding pinion-bolt 12, are carried by and mounted in suitable bearing-openings in the supporting sleeve 7, and as a means for securing lthe against a rearward rotatlon or movement after the expanding ring has b een vmoved to an expanded position,

the pinion-bolt 12, may be provided with a ratchet .Wheel 14, adapted to be engaged by outside of the Supportingsleeve 7. The ends 1, of the expanding bolts 8, and 12, are adapted to be engaged and manipulated by any suitable and convenient key for the purpose, a slot 17, (see Fig. 4) beinr provided in the side of the 'felly 1, for t e reception of the operating key just referred to.

As a means for preventing any sliding or creeping of the tire-rim of the Wheel-felly l, the latter may be provided with a plurality of transverse ribs 18, in the present instance, formed integral with the metallic band or fixed rim 4, (see Fig. 5), said transverse ribs 18being adapted to take into and engage with similarly formed transverse grooves 18a in the inner periphery of the tire-rim 5.

Having thus described my invention, Without having attempted to set forth all the forms inwhich it-may be made, or all the modes of its use, I declare that what I claim and desire to secure by Letters Patent, is:-

1. A demountable rim for vehicle wheels, comprising a Wheelfelly, a fixed rim provided With transverse ribs and a circumferential groove adapted to be closed by the tire-rim, a split ex anding ring adapted to be contracted within and to fill said groove and having its ends connected to and carrying a radially movable expanding device, and a tire-rim normally closing said groove and engaged by said transverse ribs and expanding ring.

2. A demountable rim for vehicle Wheels, comprising a fixed rim carrying anti-creeping members and a normally concealed peripheral radially expanding ring, a tire-rim engaged by said ant1creepmg members and provided with an Ainner circumferential groove normally closed by said fixed rim and engaged by said ring when the latter is in its expanded position, and means independent of said fixed rim carried by-and connected to the adjacent ends of said ring for expanding the latter.

In testimony whereof I have affixed my signature, in presence of two witnesses.
